Actuator Outputs—Actuator Controller Module
The 5009FT Control is designed to use redundant actuator outputs for each actuator or servo. Actuator
output field wiring terminations are made at the terminal strips provided on the Actuator Field Termination
Modules. Each Actuator FTM has termination points for two actuator output drivers and two RVDT or
LVDT position feedback devices. Although each FTM may drive two actuator outputs, for reasons of
redundancy the two actuators driving a single valve will originate from different FTMs. When redundant
actuator outputs are used, redundant position resolver feedbacks are not supported. For a dual coil
actuator, one driver should be wired to each coil. For a single coil actuator, wire the redundant drivers in
parallel to the coil. Refer to Figure 4-11 for supported position resolver schematics.
Wiring Notes:

Refer to Table 4-2 and Figures 4-12, 4-12a, 4-12b and
Appendix A
for Actuator Output FTM
terminal assignments.

Figure 4-11 gives feedback schematics.

Maximum impedance for a 20 to 160 mA actuator output is 45 Ω (actuator imp wire
resistance).

Each actuator driver senses its drive current to allow over- and under- current alarms and
shutdowns. Refer to Volume 3 of this manual for details on defaulted values and changing them.

It is recommended that 0.75 mm² (20 AWG) or larger twisted/shielded wire be used between each
actuator and Actuator FTM.

Shields should be connected together at all intermediate terminal blocks and terminated to earth
ground at the FTM terminal block through the Grounding Bar. The exposed wire length, beyond the
shield, should be limited to
25 mm (1”).

Do not place shielded wires in the same cable conduit with high-voltage or large-current-carrying
cables.

Cable shields must be electrically continuous from the signal source to the point the signal wire
enters the 5009FT Analog Terminal Module.

Actuator FTM terminals accept wires from 0.08–2.5 mm² (27–12 AWG) wire.

Actuator outputs are not isolated, so they should not be connected to non-isolated devices.
Some examples are shown below, refer to
Appendix A
for more information.
